Control Engineering Primer: LQR — State Feedback From Explicit Priorities
LQR derives state-feedback gains from a state-space model and a quadratic cost. This primer covers Riccati equations, observability, PID/MPC tradeoffs, robot implementation, numerical intuition, and safety.
Fundamentals · 5 minControl Engineering Primer: Model Predictive Control — Acting Within Constraints
Model Predictive Control predicts future behavior with a model, optimizes a constrained input sequence, applies only its first move, and repeats. This primer covers equations, tuning, safety, implementation, and current examples.
Fundamentals · 6 min Control Engineering Primer September 3, 2026Control Engineering Primer: Path Planning — A*, Dijkstra, RRT, RRT*, and PRM
Path planning is not drawing a shortest line. This primer compares grid and continuous-space algorithms while accounting for robot footprint, map uncertainty, computation, SLAM/Nav2 integration, and safety.

PID is not merely three gains. This primer connects its intuition and equations to sampling, saturation, anti-windup, tuning, safety, ROS 2, and real implementation checks.
Fundamentals · 7 minControl Engineering Primer: Trajectory Generation — Minimum Jerk, Quintics, and Trapezoidal Profiles
A path says where to travel; a trajectory says when and with what velocity, acceleration, and jerk. This primer covers minimum-jerk, quintic, trapezoidal profiles, constraints, safety, and ROS 2 integration.
